Description

Technical Field

[0001] This utility model belongs to the field of gasoline octane number determination technology, and in particular, a cooling device for a gasoline octane number determination machine. Background Technology

[0002] A gasoline octane rating analyzer is an instrument used to measure the anti-knock properties of gasoline, primarily for evaluating its octane number. Octane number is a crucial indicator of gasoline's ability to resist knocking in an engine, directly impacting engine performance and fuel economy. The gasoline octane rating analyzer typically performs the test through the following steps: Sample preparation: Adding the gasoline sample to the test container. Ignition: Igniting the gasoline sample in a controlled environment. Pressure monitoring: Monitoring the pressure wave generated during combustion using a pressure sensor and analyzing its characteristics. Data calculation: Calculating the gasoline's octane number based on the intensity and duration of the pressure wave. Result output: Displaying the test results on a screen for operator recording and analysis.

[0003] During gasoline combustion, the generated high-temperature gases often contain a certain amount of dust and solid particles. These particulate matter not only pollute the environment but can also adversely affect the normal operation of equipment. When these high-temperature gases are directly cooled through cooling pipes, dust and solid particles easily adhere to the inner walls of the cooling pipes, forming deposits. This deposition leads to: reduced cooling efficiency: Dust accumulation in the cooling pipes increases thermal resistance, reduces the effective heat exchange area between the coolant and the gas, thereby reducing cooling efficiency and affecting the normal operating temperature of the equipment. Increased maintenance difficulty: Once dust adheres to the inner walls of the cooling pipes, cleaning becomes complex and time-consuming. Traditional cleaning methods may be insufficient to completely remove the accumulated dirt, leading to increased equipment maintenance costs. Therefore, to address the problem of dust adhesion in the high-temperature gases generated by gasoline combustion, it is urgent to develop an effective cooling device that can reduce the adhesion of dust and solid particles while ensuring cooling efficiency, thereby improving equipment reliability and ease of maintenance.

[0004] The purpose of this invention is to provide a cooling device for a gasoline octane number tester to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for a gasoline octane number tester to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for a gasoline octane number tester, comprising a tester body for measuring the octane number of gasoline, one end of an air intake pipe connected to one side of the tester body to allow the gas generated after gasoline combustion to flow out, and the other end of the air intake pipe connected to a processing box for filtering the gas.

[0007] The processing box is equipped with a filter pipe that is connected to the air intake pipe. A limit track is provided inside the filter pipe. A filter screen is slidably connected inside the filter pipe. A limit block is connected to one side of the filter screen and is slidably connected within the limit track. A connecting plate is attached to the other side of the filter screen. An installation box connected to the filter pipe is installed on one side of the filter pipe. A first spring is connected inside the installation box. An installation groove is provided inside the connecting plate.

[0008] Furthermore, a second spring is symmetrically fixedly installed in the mounting groove, and a sliding block is connected to the other end of the second spring. The sliding block has a triangular cross-section, and a limiting groove is opened on one side of the mounting box. The shape of the sliding block is adapted to the shape of the limiting groove.

[0009] Furthermore, one end of the filter pipe is welded to a sealing valve to prevent gas leakage, and the other end is flanged to a valve.

[0010] Furthermore, a spiral cooling pipe is connected to one side of the filter pipe, and the cooling pipe passes through the treatment box and is connected to an exhaust pipe.

[0011] Furthermore, one end of the cooling pipe is connected to a support column, and the other end of the support column is fixedly installed at the bottom of the processing box.

[0012] Furthermore, a display screen and control panel are provided on one side of the measuring machine body, an air extraction valve is connected to the outside of the air outlet pipe, and a door is provided on one side of the processing box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features a filter pipe with a filter screen inside. The filter screen adsorbs dust and solid particles, effectively capturing these particles from the gas and reducing their deposition within the cooling pipe. This maintains the efficient operation of the cooling pipe, and the clean cooling pipe allows for better heat exchange, ensuring the coolant effectively removes heat and keeps the equipment within its ideal operating temperature range. By incorporating a sliding plate, a limiting groove, a first spring, and a second spring, the filter screen can be quickly and stably fixed within the filter pipe, enabling stable filtration. Simultaneously, pushing the sliding plate into the mounting groove allows the filter screen to be removed from the filter pipe, facilitating filter replacement and improving work efficiency.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] Please see Figures 1 to 5 As shown, a cooling device for a gasoline octane number tester includes a tester body 1 for measuring the octane number of gasoline. The tester body 1 is existing equipment. A gasoline sample to be tested is injected into the combustion chamber, and the flow rate is controlled by the sample injection system. Under controlled conditions, the sample is ignited, generating high-temperature gas. Temperature and pressure sensors in the combustion chamber monitor the combustion state in real time. A pressure sensor captures the pressure wave generated by combustion and transmits the data to the control system. The data processing and control system calculates the octane number of the gasoline based on the real-time data and outputs the result on the display screen 2. One end of the filter pipe 10 is welded with a protective device. The gas leak prevention valve 11 has a flange connecting a valve 12 at the other end. A spiral cooling pipe 9 is connected to one side of the filter pipe 10. The cooling pipe is used to transport cooling media (such as water, coolant, or air) to reduce the temperature of equipment or system. The cooling pipe 9 passes through the treatment box 6 and is connected to the exhaust pipe 8. One end of the support column 13 is connected to the bottom of the cooling pipe 9. The other end of the support column 13 is fixedly installed at the bottom of the treatment box 6. A display screen 2 and a control panel 3 are provided on one side of the measuring machine body 1. An exhaust valve 4 is connected to the outside of the exhaust pipe 8. A box door 7 is provided on one side of the treatment box 6.

[0028] One end of an air intake pipe 5, from which the gas produced by gasoline combustion flows, is connected to one side of the main body 1 of the measuring machine. The other end of the air intake pipe 5 is connected to a processing box 6 for filtering the gas. A filter pipe 10 is installed inside the processing box 6, and the filter pipe 10 is connected to the air intake pipe 5. A limit track 16 is provided inside the filter pipe 10. A filter screen 14 is slidably connected inside the filter pipe 10. The filter screen 14 is made of polyester mesh and has good high temperature resistance. A limit block 15 is connected to one side of the filter screen 14, and the limit block 15 is slidably connected within the limit track 16. A connecting plate 17 is glued to the other side of the filter screen 14. An installation box 23, which is connected to the filter pipe 10, is installed on one side of the filter pipe 10. A first spring 18 is connected inside the installation box 23. An installation groove 20 is provided inside the connecting plate 17.

[0029] A second spring 21 is symmetrically fixedly installed in the mounting groove 20. The other end of the second spring 21 is connected to a sliding block 22. The sliding block 22 has a triangular cross-section. This is so that the filter screen 14 can enter the filter pipe 10 and the sliding block 22 can enter the limiting groove 19. A limiting groove 19 is opened on one side of the mounting box 23. The shape of the sliding block 22 matches the shape of the limiting groove 19. The limiting block 19 can retract into the mounting groove 20.

[0030] The cooling pipe 9, the measuring machine body 1, and the air extraction valve 4 are all existing technologies. Their working principles, dimensions, and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0031] Working principle: The high-temperature gas generated when the measuring machine body 1 is measuring the octane number of gasoline enters the processing box 6 through the intake pipe 5 via the exhaust valve 4, then enters the filter pipe 10 and is filtered by the filter screen 14, then is cooled through the cooling pipe 9, and is discharged from the exhaust pipe 8.

[0032] Open the box door 7, then open the valve 12, push the sliding plate, and the sliding block 22 slides in the limiting groove 19 of the mounting box 23, so that the sliding block 22 enters the mounting groove 20 of the connecting plate 17, and the second spring 21 is compressed. In the installation state, the first spring 18 is compressed. When the sliding block 22 is released from the limiting groove 19, the first spring 18 returns to its deformation, and the filter screen 14 is pushed out. The limiting block 15 slides in the limiting track 16, so that the filter screen 14 can be taken out.
